IMPROVEMENT 1N HORSE-RAKES.

Specication forming part of Letters Patent No. 36,897, dated November ll, 1862.

To all whom it may coincer-n:

Be it known that we, G. H. DALEY and ROBT. M. TREAT, of Morris, in the county of Litchfield and State of Connecticut, have invented a new and useful Improvement in Wheeled Horse Hay-Rakes; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specitication, in which- Figure 1 is a side elevation of our horse hay rake with brake applied to it. Fig. 2 is a plan ofthe same, and Fig.3 a vertical longitudinal section of the same.

Similar letters of reference in theseveral ti gures indicate corresponding parts.

This invention consists in a friction-brake for horse hay-rakes, said brake consisting of a transverse bar, blocks, springs, connectingrods, curved foot-lever frame, and hinging brackets, all constructed and operatin g in combination with a rake-head and the Wheels ot' a horse hay-rake in such manner that the driver by pressing his foot down upon the leverframe produces frictional Contact between the wheels and the brake-blocks, and thus insures the automatic elevation and emptying of the raketeeth through the leverage of the wheels alone. Thisarrangementof brakeattachments to horse hay-rakes greatly simplifies the rake, and the parts are brought together in such manner as to be very convenient for operating and very effective in their action.

To enable others skilled in the art to makeV and use the invention, the same will now be described minutely with reference to the drawings.

A in the several figures of the drawings represents a wheeled horse hay-rake patented by Robt. M. Treat, June 10, 1862. The wheels a a revolve, and the axle b turns in the path of a circle vertically. The thills c c are jointed loosely at cl d to the axle, and the drivers seat is suspended upon the same. The rake-head B is attached rigidly to the axle by means Of a frame, c, or bars e' c', which extend out at right angles from the rear side of theraxle, and it (the rakehead) is set in rear of the wheels, and extends laterally beyond the outer faces of the same. The lever (l, by which the rakehead is raised,is fastened rigidly in the top of the axle, and is connected to the rake-head by a diagonal rod, f. This lever is retained in the brackets.

j j, screwed upon the rear ends of the bars e l e', as represented. These half-boxes form oblong slots k k between themselves and the bars, and in said slots the brake-bar D slides, so as to come, with its blocks, in frictional contact with the periphery of the wheels a a. Flat springs l lare attached to the front side ofthe brake-bar VD, and with their free ends bear against the front shoulders of the boxes j 7', and thus keep the brake-blocks out of Contact with the periphery ofthe wheels a a when the rake-head is not elevated and while the teeth thereof are raking up hay from the ground. The brake-block thus arranged is connected to the axle b by means of a curved foot-lever frame, m m' m', hinging brackets n n, and link connecting-rodsoo,asrepresented. The brackets n a screw to the under side ofthe axle at a suitable distance apart, and extend beyond the rear of the same. The lever-frame is formed of two segment-arms or side bars, m', and a transverse bar, m, and hinges by the lower ends connecting-rods link to the brake-bar D, and also to the segment-armsjustabove the hinge of The brake thus applied is readily operated, as the lever-frame extends, by reason of its curve form, under and below the drivers seat.

The operation is as follows: The driver sit ting upouthe seat with his hand upon or oli the hand-lever, the rake is drawn over the field until the teeth have collected the proper quailtit-y of hay. At this stage, it being necessary to relieve the rake-teeth of the collected hay, the driver adjusts his foot upon the part m of l the lever-frame and allows his weight to act upon it. This causes the brake bar and blocks to move up to the wheels far enough to pro duce frictional Contact between the blocks and the wheels. Now, as the machine continues to move, the wheels carry the brake and rakehead up and around with them until the teeth p i are relieved and the driver withdraws his foot ver-fran1e m m m', brackets fn, n, link connecifrom the lever-frame'. The gravity of" the rakeugrods 0 o, and brake D D D with a horse head insures its return or descent, while the hay-rake mounted upon wheels, and having a springs throw the brake-blocks out of frictional drivers seat, substantially in the manner and corqltact with the Wheels. for the purposes described.

he brake-blocks may be of leather, rubber, I A

or any other suitable materialthat is, they l may be faced with such materials.
